About the transformers
The name transformer stems from Latin (to transform). Therefore, their main function is to change the parameters of the transmitted energy of the alternate current from voltage X to voltage Y. The phenomena of electromagnetic induction and magnetic field are used. Transformers are applied everywhere there is a need to adjust the power supply parameters to the parameters of the receiver. It was owing to transformers that a possibility of relatively cheap transmission of electrical energy along great distances appeared.
Transformers are used in electrical devices and networks to change the voltage in alternate current circuits. The need for such a change results directly from the need to maximise the efficiency of transmitting electrical power along large (energy transformers – usually applied in high and medium voltage systems) and small distances (low power transformers).
A broad scope of specialist applications forces manufacturers of transformers to be able to create devices tailored to individual needs and according to predefined specifications. This group includes furnace, welding, safety or rectifier transformers.
